To all whom it may concern:

Be it known that I, EDWARD A. EVERETT, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Track- Drilling Machines, of which the following is a specification. v

This invention relates to track drilling machines and more particularly to power operated machines for drilling the rails of a railway track and has for an object to provide a machine of this type with an enclosed mechanism entirely supported by one rail of the track, that can be conveniently moved along the track, that can be quickly removed and replaced and that provides for moving the drilling mechanism out of the plane of the rail. Other objects will appear from the following specifications and drawings in which Fig. 1, is an elevation partly in section, Fig. 2 is another elevation at right angles to Fig. 1, and Fig. 3 is a. detail section taken on line a--a of Fig. 1.

This invention is intended mainly for drilling rails for bonding purposes or for the bolts of splice bars at the rail joints and consists of a gasolene motor or other source of power connected by suitable gearing with a drill spindle and includes a means for clamping the machine to the rail, for feeding the drill to the rail and for swinging the drill spindle through the arc of a circle to clear the rail.

The rail is indicated by 11, 12 and 13 are rollers supporting frame 15 on the shafts 14. 16 is the engine or motor secured to frame 15 and having the handles 17 and 18 attached thereto by which the mechanism may be conveniently rolled along the track.

The drill 21 is carried by the drill spindle 22 running in the bearings 23 and 24 supported by the casting 43. A cap 44 is provided for the end of this spindle and is removable for inspection and adjustment of the spindle. The bevel gear 25 is secured to the drill spindle engaging gear 26, secured to shaft 27 which carries bevel gear 28 engaging bevel 29 on the horizontal shaft 30. The outer end of this shaft has the belt wheel 31 splined to it by the spline 63 and belt 32 connects this wheel with the belt wheel 33 on the engine shaft adjoining the fly wheel 34. The drill spindle is thus driv en from the motor shaft by reduction gearmg which is entirely enclosed from the belt wheel {31 down to the drill spindle. This is an important feature of my invention considering its exposed use to the conditions prevallmg on a railroad track. A detachable cap 45 1s provided for the housing of gears 28 and 29 to facilitate assembly and inspection.

lformed integral with the frame 15 is the cylinder 41 Fig. 1, in which the magazine 42 is free to slide and also to rotate. A groove in the cylinder 41 is provided for the rack 51 shown in the orifice 54 of this cylinder 1n Flg. 3. This rack rests loosely on the magazine 42 and engages the rid e :32 at one end and the end plate 53 at t e other end, movement of the rack therefore moves this magazine backand forth while the magazme remains free to rotate. Enga mg the rack is the rack wheel 55 pivoted at 56 which is also the pivot of the operating handle 57. A spring controlled latch 58 looks the operating handle and rack wheel together, this latch is released by the latch handle 59.. The operating handle can thus be positioned in the most convenient operatmg position after the drill spindle is brought to bear against the rail and the magazine fed forward as the drill is operated; The spline 63 in shaft 30 permits this movement while the spindle is driven by the motor. The coil spring 60 engaging the head 61 secured to the magazine and head 62 secured to the cylinder places a bias on the.mechanism to hold the drill away from the rail and operates to quickly release the drill when the latch 59 is released as may be necessary for quickly removing the machine from the track.

The drill operating mechanism may be rotated for positioning the point of the drill at different heights on the web of the rail or adjusting it to rails of different heights and it may be rotated through 180 degrees to clear the plane of the rail when rolling the machine along the track or when the machine is transshipped from place to place. For this purpose the spade handle 46 is used to rotate the magazine 42 in the cylinder 41 about the axis of shaft 30. The magazine may be latched in any position by means of the latch ring 65 loosely mounted on the magazine 42 but keyed against rotation by the end of the rack 51 at 66. This ring is provided with teeth 67 Fig. 2 which (pivoted at 69 and having the releasing han tension toengage the latch by the spring 70. By depressin the handle 68 the latch is disengaged an the mechanism may be rotated to any position and again latched to'the ring 65.

This machine is secured to and entirely supported by one rail of the track when in the operating position. For thls purpose a three point clamp is provided for the tall head having the clamps 71 and "('2 opposite 1e 68 held in inechanism driven through said horizontal shaft, a fixed locking ring associated with said machine and means for shaft to said ring.

5. In a track drilling machine in combination, a horizontal. cylinder located on one rail of said track, a drilling mechanism arranged todrill the web of said rail, said drilling mechanism connected with said drilling machine through said cylinder, means for adjusting-the position of said drill latching said the drill, these clamps sup-port'the screw relative to said rail and means for feeding 77 the vertical height of which is adjustable in a slot as shown in Fig. 2. v The opposite side of the rail head is engaged by a toothed member 81 engaging the head on the side and beneath. This member is adjustably "secured to the cleat 80 by the screws 78, in the slot 79, Fig. '2. This cleat is secured to shaft 73 to which. the sockets 74: and 7 5 are secured. Handle 76 in socket 74 may be used to clamp the rail and can be latched in position by spring rack 82 secured to the frame engaging the notch 83 secured to the handle. This handle may be placed in socket 7 5 when the machine is operated from the opposite side and raclr 82 is provided to latch it in position similarly to rack Having thus described my invention, I claim:
